Introduction of High Temperature
Endurance Conductors - Use of special
aluminum alloy strands, INVAR reinforced
conductors can be operated at temperature
level up to 230º C as against 85/95º C for
normal ACSR Conductor. These conductors
offer thermal capacity of the order of 2 to 3
times of ACSR for same diameter and
comparable mechanical strengths. Use of
INVAR conductor in Indian power system
has been taken up on experimental basis.
Use of Compact towers for transmission
lines has reduced ROW requirement from
85 m to 64 m ( a reduction of 25% )
HotLine Maintenance – An excellent O&M
practice that has enhanced the availability
of POWERGRID’s Transmission System.
Hotline washing by helicopters
Use of helicopters for hotline washing in
geographically tough terrains, has facilitated
the process, on many occasions in a much
easier way.
Erection of Emergency Restoration
System by helicopter
The devastation caused by cyclone of
Gujarat in June 1999, Orissa in October
1999 and earthquake of Gujarat in 2001 was
attended by POWERGRID on war footing
and normalcy was restored within few days
which otherwise would have taken several
months, using Emergency Restoration
System. Use of helicopters facilitates ERS
in geographically tough terrains.
UPGRADING & UPRATING OF
TRANSMISSION LINES
Feasibility studies for Upgrading & Uprating
of Transmission Lines have already been
completed by POWERGRID for following
voltage level:
1. 66kV D/C to 132kV D/C
2. 110kV D/C to 132kV D/C
3. 132kV D/C to 400kV S/C
4. 220kV D/C to 400kV S/C (Already
implemented on Kishtwar-Kishenpur Line)
Implementation of these is proposed to be
undertaken on need basis. Further, Feasibility
studies for converting 400 kV Double Circuit lines
to HVDC Bi-poles are also underway.
Modern survey techniques for
Transmission Line
POWERGRID explored use of satellite
imageries for route alignment and preliminary
survey for its transmission lines and Air
Borne Laser Terrain Mapping (ALTM)
techniques in association with National
Remote Sensing Agency (NRSA) and
activities have been initiated to undertake
surveys using these techniques for the
forthcoming Parbati-II, Barh and Kudankulam
Projects.
E-GOVERNANCE
POWERGRID is systematically developing
competency to deploy Information Technology for
efficient and effective discharge of its functions.
Some of the salient achievements are Web
based Enterprise wide Information Portal as a
step towards E-Governance, State-of-the-Art Multi
Locational Video Conferencing System,
Inspection Management System on internet
based B2B platform, Engineering Project
management system developed in-house,
Enterprise wide Converged IT and Communication
System, Establishment of state-of-the-art 1200
node IT network infrastructure at Gurgaon office
complex with innovative features like Wi-Fi.
POWERGRID has also initiated implementation
of ERP.
POWERGRID implemented Video conferencing
facility in the capacity of technical expert cum
co-ordinator for MOP and CPSUs under MOP
and successfully completed the first consultancy
venture in IT for M/s Delhi Transco Ltd.
CONTRIBUTING TO DISTRIBUTION REFORMS
UNDER APDRP
Under Accelerated Power Development &
Reforms Program (APDRP) of Ministry of Power,
POWERGRID has been assigned the role of
Advisor-cum-Consultant (AcC) to lend its
managerial and technical expertise for developing
105 distribution circles spread over 18 States.
During 2003-04, APDRP Schemes for 35 Circles/
towns amounting to Rs. 1558 Crore were
approved where POWERGRID was Advisor cum
Consultant. In addition, POWERGRID has
undertaken implementation of APDRP schemes
worth Rs. 663 Crore on bilateral basis, in the
States of Bihar, Goa and Meghalaya.
POWERGRID is also executing Rural
Electrification works of 2400 villages in Bihar on
behalf of BSEB costing about Rs. 178 Crore,
covered under “Pradhan Mantri’s Gramodaya
Yojana (PMGY)”.
ENCOURAGING GRID DISCIPLINE
POWERGRID, in its efforts to ensure delivery of
quality power and to maintain grid discipline,
extended the implementation of Availability Based
